Technical Description, con’t
should fail. During normal operation there is absolutely no
compromise in sonic performance with this circuit, and it
ensures safe operation of the amplifier under even the most
extreme operating conditions.
In the event a problem occurs, the MC2301 Sentry
Monitor Tube Protection Circuitry will activate to prevent
potentially destructive high levels of current from flowing
in the amplifier.
Power Supply Circuits
To compliment the fully balanced design of the MC2301
the power supply utilizes a very large Power Transformer
(golf ball is for size comparison). Refer to figure 17. It is
enclosed in the legendary McIntosh Potted Enclosures.
The main filter capacitors store energy necessary for the
wide dynamic range that today’s Audio demands. Refer to
figure 16.
Most owners desire one power switch for the whole
audio system. The MC2301 is equipped with a circuit that
provides remote Power Control from a McIntosh A/V Con-
trol Center. When the A/V Control Center is switched On,
a (5-12V) signal operates the power relay in the MC2301.
The MC2301 also has a remote Power Control Out Jack.
The Power Control signal from this jack is delayed by a
fraction of a second so that the turn on power surge of
the next power amplifier occurs at a later time. This helps
prevent power circuit overload that could trip circuit break-
ers or blow fuses, a very important feature in a high power
Home Theater System employing multiple MC2301 Power
